81 x^{2} - 14 4^{2} = 11664

x = 20, x = - 20

Solution steps

81 x^{2} - 14 4^{2} = 11664

Move

14 4^{2}

to the right side

81 x^{2} = 32400

Divide both sides by

81

x^{2} = 400

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 400, x = - 400

400 = 20

- 400 = - 20

x = 20, x = - 20

1 - t^{2} = 0

3 x = (x - 4) (x - 5)

(t - 2)^{2} = - 16

x^{2} - 8 x + 21 = 6

3 w^{2} = 48
